My Father had one of those radios. I used to have fun playing with it when I was a kid. Wish I had thought to keep it when he died; but I had other things on my mind.Short wave radio that can tune 40mhz. You should get a strong signal.
Doing that makes your oscilloscope "float".My scope is a Hantek 6022BE and only connects to a laptop by a usb port. I pull the AC plug on the lap top and operate with the lap top battery.
